Hi,

tl;dr : I'm trying to make a freebsd desktop configuration
for rpi4b.

Is freebsd able to utilise the GPU part of the raspberry pi 4b?
In config.txt there can be a GPU_MEM statement for a variable size,
the remaining memory being used by the CPU. Would it make sense to
set this as large as possible for a desktop environment, or
will it simply subtract from available memory and not be used, 
or does it not have any effect at all in freebsd/xorg ?

GPU memory split appears under legacy options.

https://www.raspberrypi.com/documentation/computers/config_txt.html#legacy-options

it's not clear to me if these would even work under latest
firmware.
